Temporary mounting sheet for adhesive-surfaced articles

ABSTRACT

Temporary mounting or backing sheet to which articles having a pressure-sensitive adhesive surface are attached for the protection of the adhesive surface pending removal therefrom for use by the ultimate consumer, such articles being of the general nature of surgical pads such as corn and callous pads, finger bandages, moleskin sheets, and the like.

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention ordiscovery relates to the packaging of articles having apressure-sensitive adhesive surface thereon for sale to the ultimateconsumer. In order to protect the adhesive surface and also maintain theefficacy of the adhesive it is customary to mount the articles by way ofthe adhesive surface upon a sheet or card from which the articles may beremoved at the time of use by the ultimate consumer. The instantinvention is directed to a new form of mounting sheet. While the newmounting sheet is highly desirable for the packaging of surgical padssuch as corn or callous pads, finger bandages, sheets ofadhesive-surfaced moleskin, and the like, it will be apparent to oneskilled in the art that other nonsurgical articles may also be mountedon the sheet.

2. Description of the Prior Art For many years it was customary to mountadhesive-surfaced surgical pads and the like upon a sheet of crinolinebut such, due to its rather open weave, did not fully protect theadhesive surface from deterioration by contact with ambient air. Later,a laminated card was used for the mounting of the articles, the cardconsisting of a sheet of paper with a sheet of cellophane or acetatefilm laminated thereto as set forth in Scholl U. S. Pat. No. 2,209,210.With that arrangement, however, the articles were not as easy to removefrom the card as is desired, the underside of the articles was notvisible through the mounting, and the card was objectionably costly.Still later, as set forth in Scholl U. 3. Pat. No. 2,493,267 anirregularly crinkled vegetable parchment having a glazy surface was usedas the mounting. This, however, did not permit visibility through themounting of the underside of the articles, and the adhesive surface ofan article did not fully contact the surface of the mounting but restedupon the high points of the crinkles thereby not being fully protectedfrom ambient air, and such parchment was also objectionably expensive.

SUMMARY OF THE INVENTION The instant invention embodies a mounting sheetfor adhesive-surfaced articles which is formed of a thin plastic sheetof cellophane, acetate sheet, or equivalent material. The sheet iscorrugated and transparent. The mounting may be made by running thesheet through corrugating rolls in an extremely economical manner. Thearticle makes full contact of the adhesive with the mounting and whenthe article is removed the impression caused by the corrugations appearsin the adhesive surface of the article. The underside of each article isvisible through the mounting and the articles are very easily removedfrom the mounting especially if lifted off the mounting in the directionof the corrugations. Further, the adhesive surface is fully protecteduntil removal of the article, cannot be affected by ambient air, and themounting itself is far more economical than mountings used heretofore.Thus, it can be seen that the instant invention solved the problemsinvolved in the prior art, as above recited, and possesses advantagesnot found in the prior art.

BRIEF DESCRIPTION OF THE DRAWING FIG. I is a plan view of a mountingembodying principles of the instant invention showing a pair of corn orcallous pads disposed thereon;

FIG. 2 is a bottom plan view of the structure of FIG. I indicating thevisibility of the articles through the mounting;

FIG. 3 is a greatly enlarged vertical sectional view taken substantiallyas indicated by the line III-III of FIG. I, looking in the direction ofthe arrows;

FIG. 4 is a plan view of the same mounting carrying a sheet of moleskin;and

FIG. 5 is a view of the same mounting carrying finger bandages thereon.

DESCRIPTION OF THE PREFERRED EMBODIMENT The illustrated embodiment ofthe instant invention comprises a mounting 1 in the form of a thintransparent plastic sheet, various cellulose derivatives, acetate andvinyl sheets being satisfactory as well as other plastic sheets havingthe property to release adhesive thereon without any delamination of theadhesive from the article carrying it, are satisfactory for the purpose.

By simply passing the sheet through a pair of corrugating rolls,parallel corrugations 2 may be provided in the sheet. The sheet may thenbe cut to any desirable size depending on the size and number ofarticles to be carried by the sheet. The mounting therefore is extremelyeconomical.

In FIGS. 1, 2 and 3 I have shown the mounting with a pair ofcorn orcallous pads thereon. Each of these pads includes a cover 3 overlying abody part 4 having an affliction receiving aperture 5 therein. 0n theunderface of the body part is a spread of pressure-sensitive adhesive 6and, as clearly seen in FIG. 3, the adhesive follows the undulations ofthe corrugations so that the entire adhesive surface is fully protectedfrom ambient air, dust and dirt, by the mounting I. As seen in FIG. 2the mounting is transparent so that the undersides of the pads areplainly visible through the mounting.

The pads may very easily be removed from the mounting without anydelamination of the adhesive and without leaving any adhesive remainingon the mounting. This may be accomplished very easily be pressing flatthe corrugations adjacent the edge of the pad, bending the mounting atthe pad edge, and stripping off the pad in the direction of thecorrugations.

In addition, the mounting is flexible so that the same may be folded tobe placed in a small receptacle in a handbag, and the mounting cannot inany manner injure other delicate articles carried in the same handbag.

In FIG. 4 I have illustrated the mounting as carrying a sheet ofmoleskin having adhesive on the underside thereof. In FIG. 5 I haveillustrated the commonly known form of finger bandages 8 carried on themounting. These illustrations are by way of example only and not by wayof limitation to indicate that numerous articles bearing pressuresensitive adhesive may be utilized on the mounting to protect theadhesive until time of usage of the article.

It will be understood that modifications and variations may be effectedwithout departing from the scope of the novel concepts of the presentinvention.

I claim:

I. An article of manufacture comprising a thin sheet of transparentplastic material formed with parallel corrugations extending across thesheet between opposite edges thereof, a pad member adhering to saidsheet, said member having a pressure-sensitive adhesive coating on thesurface thereof contiguous to said sheet, said coating being in full anduninterrupted contact with the corrugations of the surface sheet, saidpad member being readily removable from said sheet.

2. The mounting of claim I, wherein said sheet is of evenly corrugatedcellophane.

3. The mounting of claim I, wherein said sheet is of evenly corrugatedacetate material.

t. The mounting of claim I, wherein said sheet is of evenly corrugatedvinyl material.
